The impact of COVID-19 on sustainable development

With more than 470 million confirmed cases of COVID-19 worldwide, and 6.1 million confirmed deaths (and perhaps three times that number, based on excess mortality as of February 27, 2022), the COVID-19 pandemic is the most important event of the 21st century so far (1,2). However, the number of people who recovered after COVID-19 as well as the newly developed vaccine have changed the course of the pandemic, and until now more than 10.8 billion vaccine doses have been administered (2).

The genome of the SARS-CoV-2 virus is composed of a single-stranded (positive-sense) RNA molecule and contains 29 903 nucleotides (3). After the first patients were reported in Wuhan, the first sequence of the virus (accession # LR757998) was released through the National Center for Biotechnology Information and European Bioinformatics Institute on January 30, 2020 (4), having been previously made public by Edward C. Holmes on January 11. Holmes, from the University of Sydney, was a member of a consortium led by Yong-Zhen Zhang of the Shanghai Public Health Clinical Center & School of Public Health, which published the sequence on https://virological.org/t/nov-el-2019-coronavirus-genome/319 as well as on GenBank (accession # MN908947). The Lancet quickly published an extensive genome analysis of the viruses extracted from nine patients. The sequences from the different patients matched at a percentage exceeding 99.98%, suggesting that the virus had only recently infiltrated the human population, most likely from a single location (5). Using a special spike-like glycoprotein on its surface, the SARS-CoV-2 virus binds to cells, mainly in the respiratory system, where it successfully uses the cell structures to produce a new generation of viruses. In the meantime, a number of scientists have shown that the so-called angiotensin-converting enzyme 2 (ACE2) receptors are key for virus entry into the cell (6). In addition to respiratory symptoms, COVID-19 patients were also diagnosed with multiple-organ involvement, including a deficiency of cellular immunity, coagulation activation, and myocardial damage, as well as liver and kidney damage (6). The increasing body of evidence suggests that chronic endothelial dysfunction is the crucial pathophysiological mechanism leading to a severe course of COVID-19 and worse patient outcomes. Cellular immunity plays an important role in people who recovered from SARS-Cov-2, presumably because that population group was exposed to several viral antigens, while in those who are vaccinated cellular immunity is created solely against the spike protein (7).
Currently, there is no way to precisely measure the total damage from the global SARS-CoV-2 pandemic. The socioeconomic impact of COVID-19 has varied among countries depending on surge inequalities, economic status, and vaccine availability when considered on a global scale. Two years ago, the COVID-19 outbreak disturbed educational systems worldwide. More recently, despite the Omicron variant, educational processes at all levels are operational and supported by safety protocols and vaccination programs. However, preliminary data suggest that the impact on the worldwide economy will be a GDP loss of at least 3.4% or approximately almost 2.96 trillion USD (8).

HOW THE VIRULENCE OF THE VIRUS BROUGHT A RAPID NEED FOR CHANGE
The incredible virulence of SARS-CoV-2 has been illustrated by Manski et al (9), who found a 10-fold increase in the probability of being tested and testing positive comparing New York and Italy between March 2020 and April 2020. Structural differences in viral variants have changed the binding affinity to the ACE2 receptors (10) and probably explain why this pandemic moved faster than those of previous iterations. This is further evidenced by increased Omicron affinity to the ACE2 receptor, caused by mutations in the receptor-binding domain (11). The rapid spread of the pandemic was compounded by an inappropriate perceived threat of the disease, which led many people to forego preventative measures such as masking. For example, one quarter of Italian health care workers did not view personal protective equipment as important (12). As such, this fast-paced pandemic with constantly mutating strains has proven difficult to contain, not only because of its virulence but also by the differential handling of it by the health care systems. The needs of society brought forth during the pandemic have resulted in tremendous steps forward by digitally transforming the distribution of goods throughout the service sector. There were also excellent examples of how society can move more efficiently toward sustainable development.
Following a good initial response by health care systems around the world, most countries' public health institutions came alive with educational public health campaigns. Many countries put into place recommen-dations and restrictions that were aimed at slowing the spread of infection. The Netherlands (13) provided excellent example of how effective public health campaigns via social media targeting could result in improved personal hygiene.

CHANGES THAT CAME ABOUT DUE TO THE AVAILABILITY OF TECHNOLOGY
This new-age approach to public health has also led to digital transformation and innovation in the technology sector. Restrictions that meant working from home for a lot of the general population created the perfect catalyst for the expansion of services such as Zoom and Microsoft Teams. In June 2019, Microsoft Teams boasted 13 million users (14), while in the second quarter of 2021 this number exponentially increased to 145 million active users (15). The Zoom meeting platform experienced a similar rise in popularity, with 10 million daily meeting participants in 2019 and as many as 350 million participants in December 2020 (16). These are phenomenal leaps responding to the many customers who wanted the same services while simultaneously wanting limited contact with the service providers. The COVID-19 pandemic has expedited the digitization of goods and services (17). The total effect is a time shift of three years globally, most notably in the Asia-Pacific markets (17). The knock-on effects of digital transformation can even be seen in the developing economies of Africa, which have several financial technology start-ups valued at over 1 billion USD. However, a severe hurdle to overcome in digital transformation is in the rural communities, which show internet usage to be only 27%, compared with 47% in urban areas (18). This illustrates the great need for further development in the provision of digital services to combat economic inequalities.

SUSTAINING DEVELOPMENT FOR THE FUTURE
We do not know if climate change will affect the transmission of SARS-CoV-2, but it is clear that climate change alters how we interact with different species on Earth. Some even underline that the COVID-19 pandemic has had a significant impact on reducing carbon emissions; however, its impact on slowing climate change is at best only temporary. The United Nations secretary-general has stated that climate change is the greatest threat to human life (19). The plans set forth in the UN's environment program will have them harness the power of digital transformation in a three-tier plan. Through a sustainable ecosystem for the planet, shifting market and customer behaviors, and digital literacy and innovation they hope to reduce carbon emissions and the use of natural resources (20). Using digital transformation, they plan to create a standardized review process to streamline inefficiencies that result in excess carbon emissions. The discrepancies in gender equality, particularly those in developing countries (21), have to be taken into account to avoid unnecessary complications of such a tremendous step in the technology sector. The sustainability of the planet for future generations is a top priority, one which we are now better prepared to deal with inadvertently thanks to the COVID-19 pandemic.

ROLE OF TECHNOLOGY IN THE COVID-19 PANDEMIC
Challenging times are always an opportunity for technological progress. Technology has unquestionably helped control the pandemic, but also facilitated the continuation of life, activities, jobs, and medical care during lockdown and periods of isolation.
At the beginning of the COVID-19 pandemic, when there were no vaccines to prevent infection and no treatment protocols to help fight the disease, basic measures such as contact tracing, quarantine, masking, and lockdown were the only methods to control the pandemic. Today, despite vaccines and greater knowledge about the disease itself, these measures still remain the first line of defense against a pandemic in many countries around the world.
An important early success was the introduction of tests, developed through biotechnology, that enabled the rapid identification of infected individuals. As early as February 2020, loop-mediated amplification (LAMP) tests were implemented and tested in China (22). Later, polymerase chain reaction (PCR)-based tests have become the gold standard, despite the fact that LAMP-based tests are faster and do not require sophisticated instrumentation. Additional tests involving antigen detection are also now commonplace, including for use at home. However, the falsepositive results obtained when using real-time reverse transcription-PCR (RT-PCR) tests to detect viral RNA, as well as the number of cycles required to reach the "cycle threshold, " have been discussed widely (23).
Although the pre-test measures had many shortcomings, digital technologies have helped in pandemic planning, surveillance, testing, contact tracing, quarantine, and health care. In some developed countries, technologies such as machine learning, artificial intelligence, real-time data from smartphones and wearable technologies (ie, smartwatches), thermal cameras, mobile phone applications, and web-based toolkits have been used for tracking, screening for infection, and contact tracing. Although advanced technologies can be expensive, require additional regulation and management, and can harm one's privacy, their use leads to faster and better isolation of infected individuals, provides a great deal of information about the disease and its prevalence, and slows the spread of infection, helping to maintain low mortality rates (24).
Digital technologies have also helped diagnose patients with severe symptoms of COVID-19. This is mostly seen in radiological diagnostics, where artificial intelligence and machine learning can differentiate COVID-19 from other lung diseases on CT scans and x-ray images, or in predicting the development of more severe forms of the disease (25,26).
Biotechnology has enabled the rapid development of the COVID-19 vaccine. The most-used vaccines against COVID-19 in the world are vaccines based on RNA technology. They are the first such vaccines licensed for use in the prevention of infectious diseases, although the RNA technology on which these vaccines are based has actually been developed over the last 20 years, but with the main goal of treating genetic diseases and cancer (27).
One of the major problems during the pandemic, especially in developing countries, was the lack of ventilators for patients with severe COVID-19, which led to poorer outcomes and lower survival rates. Advances in ventilator systems have resulted in faster ventilator production at a lower cost and thus greater ventilator availability for patients with COVID-19 (28). During the pandemic, not only did new technologies come to the fore, but some existing ones were also significantly optimized. Perhaps the best example is modern communication technologies such as video calling, which have been used for functions such as conferences, online teaching, and telemedicine.
Telemedicine is certainly not a new term in medicine, however, there has never been so much need to solve cases without the patient coming to the clinic or hospital. In the past two years, countless patients could not have come to the scheduled examination due to measures of self-isolation, or coming to the examination itself has posed a risk to the patient or the physician. These situations have led to the rapid implementation of telemedicine in almost all branches of medicine. Talking to the patient, taking a medical history, and making a preliminary examination via video calls have be-come commonplace in many developed countries (29).
Although it is impossible to see the patient fully through video, the technology has enabled useful contact between the patient and the doctor at times when a complete live examination was not possible.
Technology is advancing day by day, and in times of crisis such as the COVID-19 pandemic, advances in technology have allowed many activities to be kept afloat despite the many restrictions the pandemic brings. As a result, technological advances that came to the fore during the pandemic will continue to be used to improve education and medical care.

IMPACT OF COVID-19 ON EDUCATION
As well as all fields of life, the COVID-19 pandemic has greatly affected education. Whether it is primary and secondary school students or college students, COVID-19 has brought great changes, mostly negative, in the lives of young people.
At a time when a person, due to any contact with a SARS-CoV-2 infected individual, has to self-isolate, when often entire classes have to be quarantined due to the presence of an infected student or employee, the transition from inperson to online teaching has become commonplace.
Although today's technology makes this type of teaching easier and such teaching is a better option than the complete abolition of school and college, it brings many other potential problems. E-learning, as the only option during the peak of the pandemic, served a purpose for some subjects in schools such as language arts. However, for subjects like math and science, it was impossible to learn everything through video lessons, resulting in poorer knowledge acquisition and poorer exam grades (30).
One of the problems is that due to children not going to school, parents often need to stay at home so that the child is not alone, or hire a caretaker, which further complicates the financial situation for families. School is not only about gaining certain knowledge and qualities, but it is also about providing a safe environment for children while their parents work, about serving meals, socializing with peers, engaging in physical activity, and the acquisition of social and communication skills (30).
The lockdown profoundly affected the lives and education of college students. Even though some stu-dents could benefit from online learning, the lack of live classes and the lack of socializing with colleagues negatively affected most students' mental health, work habits, and physical activity (31).
The students who may have lost the most by switching to e-learning are medical students. Clinical rotations were stopped to prevent the spread of COVID-19 in hospitals.
Since clinical exercises are the most important and an unavoidable part of medical education, medical students lost this irreplaceable experience and knowledge. This is acknowledged by the students themselves, who mostly believe that e-learning cannot replace learning by the patient's bed (32). Furthermore, students are concerned that they will not gather enough knowledge and that they will be unprepared to finish college and start practicing medicine (33).
Attempts to compensate schools and colleges with elearning succeeded in the intention that students do not lose years of schooling, but there are gaps in knowledge in certain subjects through all levels of the institution, which can be seen especially in medicine. Medical students are the future of medicine and should be afforded the best possible education; video lectures and seminars will never be a substitute for learning in clinical rotations.

THE IMPACT OF COVID-19 ON SCIENCE AND TECHNOLOGY
The COVID-19 pandemic has resulted in various effects on socio-economic activities and caused ongoing changes in science, technology, and innovation (29). While the economic impact has mostly been negative, especially in developing countries that had slow access to both tests and vaccines, there have been some positive gains as seen by digital companies providing remote access and biotechnology companies providing tests and vaccines. As with every disaster, the challenges offer opportunities for innovation and novel responses. Biotechnology and digital providers have responded magnificently and seem likely to play key roles going forward, especially as new pandemics are likely to appear. The main downside has been that in some countries, social media has enabled the naysayers to deny that a pandemic exists. They have been quite successful in promoting anti-science views that are now having political consequences. This is an issue that scientists need to address urgently if progress is to continue.
Although it is difficult to predict the long-term effects of the COVID-19 pandemic on science, technology, and in-novation, it is important to explore all possible trends on how the pandemic could affect development in terms of overall consumption, digital infrastructure, openness, inclusiveness, and global cooperation (34). During the pandemic, various virtual communication and conferencing tools enabled new forms of collaboration between scientists, knowledge sharing, and the possibility of virtual education (35).
A larger number of scientific conferences, training activities, and research collaborations took place virtually in an attempt to increase the productivity of science and innovation. Virtual conferences have provided several benefits, such as a more diverse audience than face-to-face meetings and reduced transaction costs, as well as reducing environmental pollution by reduced airline flights. Such virtual tools have enabled access to training for a wider audience, and show high flexibility, making training more compatible with work commitments. By pooling expertise among institutions and enabling students to participate remotely in training offered by partner institutions, virtual tools could facilitate advanced education (34). However, there has been a cost in creativity as most professionals acknowledge that new and unexpected ideas arise much more easily during in-person meetings. After 25 years of tradition, the 2021 iteration of the ISABS conference was skipped due to COVID-19. After all possible efforts made to hold "The 12th ISABS Conference on Forensic and Anthropologic Genetics and Mayo Clinic Lectures in Individualized Medicine, " in-person attendance will be possible in beautiful Dubrovnik during June of this year (36).
The development of rapid information transfer has made it possible in the event of another future pandemic to accelerate the automation and business adoption of other technologies and practices. Results from companies that have successfully responded to the crisis during the pandemic point to many technological capabilities that others do not have -above all, filling gaps in technological advances during the pandemic, using more advanced technologies, and speed in experimentation and innovation (34,37).
The pandemic has also stimulated investment in blockchain technologies to increase transparency and trust in supply chains. Furthermore, trade barriers and relocation of production to locations where work is less expensive can further contribute to facilitating the process (34). The COVID-19 pandemic has shown the value and importance of new and improved forms of scientific communication such as the amount of data published on preprint servers and the way it is reviewed on social media platforms before official peer review. In that way, manuscripts and data can be quickly viewed, edited, analyzed, and published (38).

THE IMPACT OF COVID-19 ON EMERGING TECHNOLOGIES IN CELL AND GENE THERAPY
Gene and cell therapies represent innovations for the treatment of severe and inherited diseases, such as cancer, as well as rare genetic disorders and metabolic diseases. The COVID-19 pandemic disrupted the production and delivery of treatments and suspended research and the clinical development of various therapeutic options that are crucial for the gene and cell therapy (40).
The pharmaceutical industry, along with other key economic sectors, was severely disrupted during the COVID-19 pandemic as a result of investment in vaccines and the development of drugs against the SARS-CoV-2 virus. Stopping the development of other drugs has been particularly detrimental to the gene and cell therapy industry due to its complexity in production, supply chains, significant cost, and clinical trials. Some gene therapy development companies have shifted to the development of mRNA vaccines with similar technology. On the other hand, the COVID-19 pandemic has provided great opportunities for the pharmaceutical industry, exemplified by the need to rapidly develop drugs and vaccines against COVID-19.
Companies that have developed gene and cell therapy had extensive experience in molecular biology, cellular immunity, genomic technology, and the production of viral vectors. These characteristics put them at an advantage in the research and development of promising therapies for COVID-19 (41).
The COVID-19 pandemic led to an unprecedented situation that affected all aspects of life, leading to un-certainty before the companies published the results of phase III clinical trials for two different mRNA-based vaccines (42). Thus, COVID-19 vaccines became the first licensed drugs to prevent infectious diseases using mRNA technology, although RNA vaccines and vector vaccines against adenovirus have been developed for more than 20 years for use in cancer and diseases caused by genetic mutations. Vaccines against COVID-19 very effectively prevent the disease in a relatively short period, however, their safety and efficacy will need to be monitored in the following years (27).
On the other hand, the COVID-19 pandemic has produced research and development of other forms of cancer therapy around the world, such as chimeric antigen receptor (CAR) T-cell therapy. Available data on the impact of the COVID-19 pandemic-related constraints on CAR T-cell delivery indicate the influence of pandemic waves and complement data from the biopharmaceutical industry highlighting the pandemic's impact on cell and gene therapy detection and the delivery of licensed products (43). Nevertheless, some of the newer molecular technologies such as the rapidly advancing CRISPR technology may aid in tackling a global pandemic. During the COVID-19 pandemic, an urgent response was required to develop rapid and effective testing and diagnostic tools as soon as possible, alongside treatment options for patients with COVID-19 infection. Recently developed COVID-19 CRISPR Cas12-based test called SARS-CoV-2 DETECTR shows a short time of about 40 minutes to obtain results and an accuracy of 95%. In addition to CRIS-PR's molecular technology, CRISPR is potentially a tool for developing therapeutic options for patients with COVID-19. A Cas13 RNA-guided RNA-targeted endonuclease has recently been discovered and may serve as a potential therapeutic agent against COVID-19 (44).
In addition, successful treatment with mesenchymal stem cell therapy of patients with a severe clinical picture of COVID-19 has been demonstrated during the pandemic (45). Thus, the COVID-19 crisis has led to the accelerated and necessary use of the latest cellular and gene therapies, whose effectiveness and safety have yet to be clarified.

CONCLUDING REMARkS
The COVID-19 pandemic has demonstrated the previous fragility of our health care systems, which generally were unprepared for such a ferocious outbreak. However, it has also demonstrated the importance of biotechnology and digital technology in responding to the major challenge of a global pandemic. Thanks to previous developments in both fields, work, education, and daily living mostly managed to survive this pandemic and showed how important previous research was in providing the necessary tools, such as rapid diagnostic testing and vaccine development as well as remote video communication. In all three cases, the newly developed technologies promise that future responses to pandemics will likely be much more impactful than they had been previously. The pandemic also highlighted the shortcomings in response such as the inequality between urban and rural areas and between the developed world and the developing world. These issues will need to be addressed if we are to ensure a sustainable future for the planet. Even though it became the subject of interest for many, in this article we did not discuss the impact of different complications after recovering from COVID-19 or different sequelae after COVID-19 vaccination, simply because we still do not have relevant studies that gave clear answers to these questions.
In addition to health and communication issues, the availability of food in both developed and developing countries showed a sharp contrast and raised awareness of the need to do much better. Developing countries, in particular, need greater improvements in agricultural practices to ensure that populations can obtain sufficient nutritious food to respond both to pandemics and to the basic needs of life. It is time to recognize the value of crops that have been improved by biotechnology, so-called genetically modified crops. Science has demonstrated that such biotechnologically-improved crops are safe and do not need the draconian regulations that are preventing their widespread use.
Surely, by now we have learnt that politicians must respond to the needs of the world population and not to local self-interest. We all came together to fight the pandemic. Let us do the same to ensure a sustainable future for the planet.
